Speaker: Bharat Bhargava, Dept. of Computer Science, Purdue UniversityAbstract: Lack of trust, privacy, security, and reliability impedes information sharing among distributed entities. My research work focuses on the creation of knowledge and learning in secure networking, systems, and applications. The fundamental research problems include: intruder identification, trust management, privacy preserved interactions, and dealing with a variety of attacks and frauds. The integrated results will provide guidelines for the design and deployment of security sensitive applications in the next generation networks.In this talk, I will present intruder identification in AODV protocol for establishing routes. By monitoring the routing information, attacks such as false destination sequence numbers are detected. A protocol called RLR (Reverse Labeling Restriction) is presented to identify and isolate the malicious hosts in ad hoc networks. Simulation results show that up to 95% of the normal hosts can successfully identify all attackers. Isolating the malicious hosts through rejecting routing information from them causes a 30% increase in the data delivery ratio. The robustness analysis shows that RLR does not introduce additional vulnerabilities. We believe that RLR can be easily ported to other ad hoc network routing protocols.We are extending this research to deal with collaborative attacks. Congestion avoidance, wormhole attacks, authentication, and privacy are being studied for routing protocols.Speaker Bio: Bharat Bhargava is a professor of the department of computer sciences with a courtesy appointment in the school of electrical and computer engineering at Purdue University. Professor Bhargava is conducting research in security and privacy issues in distributed systems. This involves host authentication and key management, secure routing and dealing with malicious hosts, adaptability to attacks, and experimental studies. Related research is in formalizing evidence, trust, and fraud. These ideas are being applied to the building of peer-to-peer systems, cellular assisted mobile ad-hoc networks, and to the monitoring of QoS enabled network domains.Professor Bhargava is a Fellow of the IEEE and the IETE. He has been awarded the charter Gold Core Member distinction by the IEEE Computer Society for his distinguished service. In 1999 he received IEEE Technical Achievement award for a major impact of his decade long contributions to foundations of adaptability in communication and distributed systems. In 2003, he has been inducted in the Purdue's book of great teachers. He serves on five editorial boards of international journals, and is the founder of the IEEE Symposium on Reliable and Distributed Systems, IEEE Conference on Digital Library, ACM Conference on Information and Knowledge Management.Host: Bhaskar Krishnamachari; bkrishna@usc.edu
